MOLDING-IVIACHINE.

SPECIFICATION forming part of Letters Patent No. 792,044, dated June 13, 1905. Application filed June '7, 1904. Serial No. 211,562.

To @ZZ whom it may concern.-

Beit known that I, CHARLES HENRY HU'rcH- INGS, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Molding-Machines; and I hereby declare that the following is a full, clear, and exact description of the same. This invention relates to a machine for molding cementing and siliceous substances intimately mixed together in a dry state and then slightly moistened to cause their adhesion when tamped or pressed into a homogeneous mass. Owing to the granular nature of the mixture, it is necessary to handle the molded block with the greatest of care during its delivery from the molding-machine and its transportation to the hardening or seasoning room.

In my former patent, No. 714,184, dated November 25, 1902, I have shown and described a molding-machine in which the mold-box or flask was rigidly maintained in an upright position and iitted with a removable followboard upon which the molded block was removed. During the operation of that machine it was necessary to exercise more than ordinary care and skill in the removal of the molded block from the mold-box or iiask, and often under the most careful conditions the homogeneity of the molded mixture was frequently shattered and the block rendered useless for the purpose for which it was intended.

The object of the present invention is to articulatingly connect the mold-box or iiask to the frame of the machine, so that it can be maintained in an upright position during the molding of the material and then turned into a position at substantially right angles thereto to deliver the molded block to a movable carriage positioned to receive it.

For a full understanding of the invention reference is to be had to the following description and to the accompanying drawings, in which- Figure l is a front elevation of the machine. Fig. 2 is an end elevation showing' the mold in the upright position. Fig. 3 is a similar view to Fig. 2, showing the mold in its upset position. Fig. 4t is a transverse sectional view of the machine with the mold in the position shown in Fig'. 3. Fig. 5 is a similar view to Fig. 3 with the clamping-lever and end plates for the mold released from engagement with the xed and detachable sides. Fig. 6 is a detail view of one of the end plates and operating-levers. Fig. 7 is a plan view of the top of a section of the mold, showing the clamping members for locking the end plates and lixed and detachable sides together. Fig. 8 is a sectional view showing the carriage and carriage-operating mechanism, and Fig. 9 is a view of a section of the mold.

Like letters of reference refer to like parts throughout the specification and drawings.

Stationarily mounted upon the top of the frame a are four transversely-disposed-rails each having a V-shaped groove c, and mounted upon the rails are the'carriage-slides (Z, having V-shaped tongues f to enter the grooves c and prevent their lateral displacement from the rails. Journaled in the ends of the frame t is a longitudinally-disposed shaft g, located below the rails and fitted at each end with a lever L, by means of which it is actuated, and mounted upon the shaft g intermediate its ends are cranks c', connected by links j to the carriage e. During the operation of the levers the shaft g is rotated to cause the cranks t' and links j'to move the carriage either toward the back or front of the carriage-bedthat is to say, if the levers /t are moved in the direction indicated by arrow the shaft g and the cranks z' will execute a corresponding movement and cause the links to draw the carriage toward the front of the machine, while the reverse movement will cause them to move it toward the back of the machine. Projecting upwardly from the top of the standards a are vertical arms 7s, to which are hinged the downward extensions Z'of the mold-box, which is shown to consist of a bottom plate m, integrally formed with or permanently connected to the downward extensions l, and a side plate o, integrally formed with or permanently connected to the bottom plate m, and a removable side plate p, detachably connected to the bottom plate im at the front of the mold-box by hook-shaped clamps q, .projecting forwardly from the under side of the bottom plate m. To rigidly lock the removable side plate p to the bottom plate fm when the parts are in their assembled condition, the end plates fr for the mold-box are fitted with clamping-levers s, having clamping-hooks and u to engage, respectively, the hook-shaped arms o, projecting endwise from the removable side plate p, and the clamping-cams w, formed on the back surface of the side plate o. The clamping-levers s are fulcrumed to the outer faces of the end plates fr, and when the clamping-hooks t and u are brought into engagement with the hook-shaped arms and clamps thefend plates are forced `tightly against the ends of the side plates o and p and the removable side plate is drawn tightly into position against the adjacent stops fr on the inner faces of the end plates yr, which are also litted with stops af to engage the side plate o and hold the end plates immovable when locked by the clamping-levers. Attached to the mold-box are handles with projections e extending below the bottom of the mold-box to engage the frame a when the mold-box is in its upright position to limit its motion and to hold it an upright position while the material is being molded.

The operation of the invention is as follows: In molding a block the mold-box is placed in an upright position with the projections e engaging' the back of the frame fr, to rigidly hold it in such a position until the molding operation has been completed. The removable side plate p is then placed in position upon the clamps q and the end plates yr positioned against the end and bottom plates. The clamping-levers are then actuated to engage the hook-shaped arms and cams to draw the component parts of the mold-box .rigidly together. The levers 7:/ are then actuated to position the carriage e where it will be engaged by the removable side plate 7J when the moldbox is upset. The material is then placed in the mold-box and tamped or pressed to therequired shape and density, and the mold-box is then turned into an upset positiom so that the removable plate j) will rest upon the carriage c. The clamping-levers s are then actuated to disengage the clamping-hooks from the hook-shaped arms and cams, and the end plates are then rotated upon their pivots a", so as to drop below and be entirely clear of contact with the end and bottom plates of the moldbox. rI`he levers /L are then actuated to draw the carriage with the removable side plate p, with its load, away from the mold-box and to ward the front of the machine without shattering or destroying its homogeneity, so that when it is moved forward sut'ciently to clear the mold-box the removable side plate and its load can be raised from the carriage and transported to the place where it is to season and harden.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, isa
